Top 10 Health Benefits of Low-level Laser Therapy

The Mladenoff Clinic of Arizona Team • September 27, 2023

If you have been keeping up with the recent wellness trends, you may have come across low level laser treatments and be wondering about the health benefits of cold-laser technology.

Low-level laser therapy (LLLT), also known as cold laser therapy or photobiomodulation (PBM) therapy, is a non-invasive, low-intensity light therapy that has been approved by the U.S. Food & Drug Administration (FDA) to stimulate healing. In contrast to standard lasers often used in surgery to apply intense heat to make incisions, the light intensity in LLLT is too low to heat the body’s tissues.

Specifically, the application of red and near infra-red light over injuries or lesions may improve wound and soft tissue healing, reduce inflammation, and relieve acute and chronic pain, especially musculoskeletal pain.

What’s cold laser therapy? Cold laser therapy is low-intensity laser therapy that stimulates healing while using low levels of light. The technique is called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. The level of light is low when compared to other forms of laser therapy, such as those used to destroy tumors and coagulate tissue. Surgical and aesthetic lasers heat the tissue being treated. True to its name, cold laser therapy does not. Cold laser therapy is also known as:

  • low-level laser therapy (LLLT)
  • low-power laser therapy (LPLT)
  • soft laser biostimulation
  • photobiomodulation

Potential Benefits of Low-Level Laser Therapy

Clinical trials and studies of low-level laser therapy suggest many beneficial effects, including:

1. Alleviates pain (analgesic): Low-level laser therapy alleviates pain in the following ways:

  • Partially blocks pain signals from nerves to the brain
  • Decreases nerve sensitivity
  • Reduces inflammation ( see No. 3 below )
  • Stimulates the production of high levels of pain-killing chemicals including endorphins, enkephalins, and opioids in the brain and adrenal glands
  • Stimulates muscle trigger points and acupuncture points non-invasively to relax contracted muscle fibers
2. Supports detoxification and removes fat that may stimulate weight loss: Low-level laser therapy liquifies the fatty content contained in fat cells and disrupts the membranes of these cells, inducing the formation of transitory pores that enable the liquified fat to seep out of the cells into spaces where the lymphatic system can begin to flush it from the body.

3. Reduces inflammation: Low-level laser therapy dilates blood vessels and activates the lymphatic system to drain swollen areas that are the result of trauma or inflammation.

4. Accelerates cell growth and tissue repair: Low-intensity light penetrates deep into tissues to accelerate cell reproduction and growth and increase energy availability to cells. It enhances cell metabolism by increasing adenosine triphosphate (ADP) production, which improves cell nutrition and waste elimination, which is especially effective in repairing tendons, ligaments, and muscles. It also stimulates fibroblast development in damaged tissue ( fibroblasts are the building blocks of collage , the essential protein required to replace old tissue or repair tissue injuries), making LLLT especially helpful in treating burns and open wounds.

5. Enhances vascular activity: Low-level laser therapy speeds the healing process, closes wounds more quickly, and reduces scarring in two ways:

  • Significantly increases the formation of new capillaries in damaged tissue
  • Dilates blood vessels (increases their diameter), thereby improving the flow of blood to damaged tissues

6. Increases metabolic activity: Low-level laser therapy stimulates higher outputs of specific pro-healing enzymes in blood cells, along with improved oxygen and nutrient delivery.

7. Reduces formation of scar tissue: Low-level laser therapy reduces the formation of fibrous (scar) tissue from cuts, scratches, burns, or surgery.

8. Enhances nerve regeneration and function: Low-level laser therapy speeds up the process of axonal regeneration and nerve cell reconnection.

9. Supports immune system function: Low-level laser therapy directly affects immune function by stimulating the production of immunoglobulins and lymphocytes and by improving the ease of penetration of white blood cells into damaged tissue.

10. Reduces reliance on medications: Low-level laser therapy is considered a safe, natural, and effective alternative therapy that may help reduce or eliminate the need for opioids and other analgesics, anti-inflammatories, and other medications that may have undesirable side effects.

Low Level Laser Therapy Uses

Low-level laser therapy has a wide range of applications, including the following:

  • Musculoskeletal injuries and pain: Sprains (muscles and ligaments), tendonitis, bursitis, tennis elbow, neck pain, lower back pain, knee pain, muscle spasms, joint swelling.

  • Inflammation: Inflamed gums, carpal tunnel syndrome, and inflammation caused by autoimmune conditions (such as rheumatoid arthritis and fibromyalgia).

  • Wound healing: For wounds that resist treatment, such as those related to diabetes.

  • Detoxification, fat loss, and weight management: When used as a complimentary element of an integrative plan of care, low-level laser therapy — like the protocol now available with Dr. D — may aid the body in eliminating excess fat that could be contributing to dysfunction or chronic illness.

  • Acupuncture: For patients who are uncomfortable with needles.

  • Skin rejuvenation: Acne, psoriasis, burns, vitiligo, dermatitis, rashes, edema (swelling).

As loving and caring parents, we naturally want to help our children feel better when the inevitable fevers, colds, and illnesses arise. Many of us will reach for popular over-the-counter remedies to suppress fever and alleviate symptoms, in the belief that these products are reliable. Yet, it is important to recognize that by suppressing fever, we are suppressing a critical immune response—one that has a necessary function in fighting illness. I can attest to the enormous fear that fever provokes in parents. By far, the greatest number of after-hours telephone calls are questions regarding the “management” of fever with drugs. Undue attention to a child’s temperature and mishandling of fevers generate a great deal of unwarranted parental anxiety, avoidable medical complications, and countless calls and costly visits to doctors and emergency rooms. As long as we remain captive to the medical myth that nature made a mistake in causing a fever during illness, our children will be put at risk. Yes, fever can be uncomfortable. A child with a high fever will often seem irritable, lethargic, glassy eyed, and listless. This alerts you that the body is mobilizing defense against disease and you, in turn, must care for your child in the most appropriate way: encouraging rest and fluids. On the other hand, there may be no reason to treat even a high fever if your child seems happy, active and alert. The pervasive belief that fever is dangerous and must be suppressed disregards the scientific evidence demonstrating its beneficial role in inflammatory diseases. The immune system depends on the fever to accomplish myriad tasks when gearing up to fight infections. “Fever phobia” is made worse by hearing myths about children being severely harmed by having a high fever. Many people know of children or adults who had a high fever and ended up with some sort of injury…brain damage or hearing loss. These problems are never caused by fever. The likely explanation is that they had a serious illness that gave them a fever, but it was the illness that caused the brain damage or other result. The fever was only the body’s attempt to fight the infection. “Doctors do a great disservice to you and your child when they prescribe drugs to reduce fever,” writes Dr. Robert Mendelsohn, pediatrician and author of How to Raise a Healthy Child In Spite of Your Doctor. “Fever phobia is a disease of pediatricians, not parents, and to the extent that parents are victimized by it, doctors are at fault.” Parents are left to fear that their child’s temperature will keep rising unless measures are taken to control it. Yet, reducing the child’s temperature will do nothing to make the child well, and our bodies have a built-in mechanism that will prevent an infection-induced temperature from reaching dangerous levels. Mendelsohn emphasizes that “only in the case of heatstroke, poisoning, or other externally caused fevers is this body mechanism overwhelmed and inoperative.” “Fever: Your Body’s Defense Against Disease” is the title of Chapter 7 in Dr. Mendelsohn’s book, an excellent resource for parents seeking a balanced and accurate perspective of the beneficial role of fevers in childhood. Dr. Mendelsohn condemns the useless and dangerous practice of fever suppression through drugs, and counters the myth that high fever causes seizures. “Many parents are fearful of fevers because they have witnessed a convulsive seizure and believe their child may experience one if the body temperature is allowed to rise too high. High fevers do not cause convulsions. They result when the temperature rises at an extremely rapid rate and are relatively uncommon.” Only a small percentage of children with high fever experience convulsions, and those who do suffer them do not have any aftereffects. Simple febrile seizures are self-limited and harmless, although they are one of the most frightening things that a parent can witness. Dr. Mendelsohn continues, “Fevers produced by viral or bacterial infections will not cause brain damage or permanent physical harm. Fevers are a common symptom in children and are not an indication of serious illness unless associated with major changes in appearance and behavior or other additional symptoms such as respiratory difficulty, extreme listlessness, or loss of consciousness. The height of fever is not a measure of the severity of the illness.” A child who appears very ill with a fever of 101°F would be much more of a concern to me than a child who feels fine, is drinking and playing, but has a fever of 105°F. Numerous studies have shown that fever enhances the immune response by disabling bacteria and viruses. Also, with a rise in temperature, iron is removed from the blood and stored in the liver, further disabling the rate at which bacteria can multiply. As a note of caution, when a fever arises in a newborn in the first few weeks after birth, there is a heightened level of concern. “Newborn babies may suffer infections related to obstetrical interventions during delivery, …aspiration pneumonia from amniotic fluid forced into the lungs because of overmedication of the mother during delivery…and exposure to the legion of germs that abound in the hospital itself,” writes Dr. Mendelsohn. Parents are advised to seek medical help if a baby runs a fever in the first two months after birth. As breastfeeding plays a critical role in preventing infections in infants, breastfed babies are superbly protected against a vast range of pathogens and have a lesser risk of developing fevers in the newborn phase. Mistrust of natural processes and reliance on drug-oriented medicine has obscured parents’ understanding of the importance of childhood illnesses and the necessity of fever as a vital aspect of the immune system. When a child has a fever, it is not necessary to artificially lower the temperature. It is, however, important for the child to take in plenty of fluids, because in this time of elevated body temperature, it is easy to become dehydrated. Broth, liquid electrolytes, and fruit juices are great choices because they replace electrolytes that are used up in the fever process. Rest during times of fever will allow the body to use its energy to fight off infection. Make a commitment to spend time with your sick child. Any time that you feel concerned about the way your child is acting, or if your instinct is that something is wrong, do not hesitate to call your doctor.

Have you ever noticed how stress settles in your shoulders, anxiety affects your stomach, or grief feels heavy in your chest? While modern medicine recognizes that emotional stress can influence physical health, Traditional Chinese Medicine (TCM) has explored this mind-body connection for thousands of years.  In TCM, emotions and physical health are deeply interconnected. Each major organ system is associated with specific emotional patterns, and maintaining balance is thought to support both emotional and physical well-being.
